Zusammenfassung:Low‐aspect‐ratio Si nanohemisphere‐array surface texturing applicable to ultrathin‐film solar cells is introduced to improve cell performance. Besides the excellent light confinement, the low‐aspect‐ratio characteristic of the Si nanohemispheres facilitates the formation of high‐quality p–n junctions and electrical contacts, relative to their high‐aspect‐ratio counterparts such as Si nanowires.
